MPCNC mount for Chinese 400W spindle (52mm)

This is a mount for MPCNC to hold a 400W Chinese spindle (diameter 52mm). You need to print 2 pcs to hold the spindle firmly.

I designed this with Fusion 360 and include here the source files in case you need to edit something (for example the nut size).

Here's a link to ebay for the spindle:
